Сократите дроби
Пожалуйста

Answer 1

$a) \frac{18 \times 7 - 18 \times 5}{24 \times 7 + 24 \times 5} = \frac{18(7 - 5)}{24(7 + 5)} = \frac{18 \times 2}{24 \times 12} = \frac{6 \times 6}{6 \times 6 \times 8} = \frac{1}{8}$
$b) \frac{28 \times 2 + 28 \times 6}{42 \times 6 - 42 \times 2} = \frac{28(2 + 6)}{42(6 - 2)} = \frac{28 \times 8}{42 \times 4} = \frac{7 \times 4 \times 8}{7 \times 6 \times 4} = \frac{4}{3} = 1 \frac{1}{3}$
